I have a Payne AC and forced air furnace.
Wire colors on current thermostat:
Blue to terminal C
Green to Terminal G
Yellow to terminal Y
White to Terminal W
Red to terminal RH
Black jumper wire RH to RC
No X terminal. It does have a B and O terminal but no wires are
connected.
I have installed thermostats before without any problem. This has
turned out to be a different story.
